Very curious to see just what, exactly, you think the purpose is for a like/dislike voting system on videos?(So I guess that what I've learned today, from several people in fact, is that it is perfectly valid and not in any way abuse of the video rating system to mass downvote videos from someone you don't like or agree with or have some other issue with. Well, you have fun with that logic/morals.
At least Mike's back, despite all that.)
